...as before, tracks on copyrighted retail music CDs are in CDA format. If you try dragging and dropping a CDA file (a track) from the CD to a folder on the Hard Drive, it will simply create a link to the track on the CD.
CDEX is another good, free CD Ripper for ripping tracks to MP3, WAV, OGG and some other formats (but no WMA support):
O yea, I'm just used to coping MP3 CDs and not regular ones. All the ones I ever copied were MP3 format (because burning MP3 disks is SOOO much faster then regular audio), and I haven't bought a retail CD for a long time, I either get it the "free" way or my friends make me a copy (which they also use MP3 format).
